Abstract

Waste water, for example municipal waste water including sewage, is treated by a method which comprises adding a particulate material to the waste water, and then performing a flotation process so that the particulate material rises to the surface of the waste water, entraining solids material in the waste water. The particulate material may comprise buoyant particles, or, if the flotation process includes the generation of gas bubbles within the waste water, particles which are slightly more dense than water but become buoyant as the gas bubbles agglomerate on the particles. The particles may comprise bubbles of soda-lime-borosilicate glass.
